I noticed that sadness is something that cannot be cut into two. So it is immaterial. A meaningless world is also a concept that is also immaterial. So since the world could be meaningless...it probably is meaningless. And since sadness is part of the make-up of a meaningless world...then the world MUST be meaningless. It's amazing how sadness (as well as genocide, female circumcision and tsunamis) fit so perfectly into this world.
